With reference to figure 1, the exemplary embodiment that, also is called the end cap 100 of " end closure " here according to the present invention is inserted sleeve 12 so that form insertion container or package 10.Complete package/container 10 forms by the sleeve 12 that is furnished with end cap at its at least one place, end; But, as selection, and shown in exemplary embodiment, just the package that forms complete closed is sentenced at the two ends that end cap 100,16 can be arranged in sleeve.
In the exemplary embodiment of Fig. 1, the lower end of sleeve 12 has the end cap 16 that can not unclamp.The lower end of edge 32 coupling spools 12 of end cap 16, and prevent that end cap 16 from inserting sleeve 12 fully.The lock tabs 20 of the lockout mechanism that can not unclamp by the sleeve 12 in the passage 24 that places end cap 16 collaboratively of end cap 16 withdrawal that prevents the lower end of sleeve 12 partly forms.Lockout mechanism is finished by the flange 36 of the periphery of the passage 24 of qualification end cap 16.Flange 36 engages lock tabs 20 so that finally prevent end cap 16 dismountings.The compartment 28 that is used to receive article also can be arranged in the end cap 16.In certain embodiments, the end cap at place, sleeve opposite end all is the type that can not unclamp, so that form the package that is not easy near content.
Simultaneously with reference to Fig. 1 and 2, the exemplary embodiment according to end cap 100 of the present invention or closure member is described in further detail now.The decomposition view of Fig. 2 is the details of the exemplary embodiment of the end cap 100 of presentation graphs 1 more clearly.Releasable end cap 100 comprises the housing 102 that is applicable to the band wall that is received closely by sleeve 12.For example, housing 102 can have and the corresponding cross-sectional configuration of the cross-sectional configuration of sleeve 12, as shown, makes housing 102 to be received closely by sleeve 12.Housing 102 is slightly elongated at least, helps end cap 100 to insert sleeve 12.The periphery of one end of housing 102 comprises edge 104.Being applicable to the end of coupling spool 12 as the edge 104 of collar-like element inserts fully so that prevent end cap 100.Housing 102 has and is applicable to the path 10 6 of the lock tabs 18 of the upper end of coupling spool 12 collaboratively.The lower end of inserting the housing 102 of sleeve 12 is expressed as closing end 108, but can be configured to open construction, and does not depart from instruction of the present invention.
Housing 102 is strengthened by the corbeling 120 that extends between the zone of housing 102.Corbeling 120 can extend between the zone of housing 102 near the opening of the flange perimeter 104 that forms housing 102.Shown in the exemplary embodiment of end cap 100, corbeling 120 is by extending between the zone of housing 102 on the flange perimeter 104 that is fixed on housing 102.
With reference to figure 3 and 4, the exemplary embodiment of corbeling 120 is the lids with periphery 124 and inner 122 simultaneously.Lid corbeling 120 is applicable on the edge 104 that is attached at housing 102.Though corbeling 120 can be taked many forms, it is characterized in that the wall part of its support housing 102 so that provide structural integrity and rigidity.When being applied to the top of housing 102, corbeling 120 provides enough rigidity, makes to unclamp to cover that closure member/lid 100 reverses and indeformable, and simultaneously, causes sleeve 12 to be out of shape to help end cap 100 to unclamp from sleeve 12.
Use the reinforcement end cap that discloses as the present invention, provide the closure member that keeps its form at the place, the end that can not operate of package, and be positioned to be not easy distortion.
The end cap of making in accordance with the teachings of the present invention 100,16 can be made by multiple material and multiple manufacture method; But, of the present invention particularly useful when being taught in the end cap that is used for making by thermo shaping method.Compare with other plastics manufacture method of for example injection-molded, adopt the plastic working of thermo shaping method to provide processing not too expensive end product usually.Thermoforming provides the advantage that is better than injection molding process.Hot formed cost advantage is to compare with other method of for example injection-molded, uses less raw MAT'L usually.Another advantage is to reduce to form the cost of the mould of manufacture component.The cost of hot formed mould can be low to moderate 14% of injection-molded die cost.In addition, yield heterosis is that thermo shaping method made 3.5 times product of the number of articles of making in the injection molding conversion operations process.
The latent defect of thermoforming end cap is that it can lack enough rigidity and be provided at and be not easy crackle and indeformable end closure product when reversing.Corbeling 120 provides the end cap resistance to deformation required desired stiffness.Lid corbeling 120 provides the simple mono-device of strengthening housing 102.
Corbeling 120 can and be attached in the housing 102 by multiple manufacture method or process manufacturing.For example, corbeling can form whole with housing 102.As another example, a part and housing that corbeling can be used as the thermoforming process form integral body.
Corbeling can separately form by several different methods, and then is fixed on the housing.For example, corbeling can independently form by comprising hot formed any method, and then is fixed on the housing.In addition, corbeling 120 can be by cutting or with the peripheral shape corresponding structure of other mode with the upper, open end of substrate sheet formation and housing 102.Substrate can be selected from including, but not limited to the material of plastics, paper, cardboard and laminate thereof and analogue.
Lid corbeling 120 can be fixed on the housing 102 in several ways, so that article or parts are combined with another article or parts.This method comprises method or its any combination that is applicable in conjunction with plastics-plastics, paper-paper, cardboard-cardboard.In addition, if housing 102 and lid corbeling 120 are all formed by thermoforming, they for example will all comprise the material of the plastics that form by thermoforming, be applicable to by using frequency of radio (RF) electromagnetic radiation heating and sealing to mutually combine.But in conjunction with all comprising sonic seal and adhesives combination by plastics housing 102 that forms and the system of selection of covering corbeling 120.In addition, housing 102 and Gai Ke are adjusted and are configured to by one of them being pressed into the Lock Part that another comes the complementation of combination.
Whether corbeling 120 can extend between the zone of housing 102, and not at the upper end of housing 102, form whole with housing 102 regardless of it.
When corbeling 120 was configured to cover, another advantage of the present invention was that the inside of housing 102 can be used as the compartment of complementary article.Using another advantage of the corbeling of the form of covering to be that the in-to-in outside face of corbeling/lid or inside face can be used to show writes or the convex sign.
Law does not require and does not allow economically to illustrate and instruct each possible embodiment of current claim.Therefore, described embodiment is that the exemplary illustration of disclosed application is understood the principle of the invention so that know.Can carry out modification, remodeling and combination for described embodiment and do not depart from the scope of claim.All these modification, remodeling and combinations comprise by this disclosure and claim subsequently here.
